VEHICLE-BRAKE.

SPEGIFICATION forming part of Letters Patent N0. 763,095, dated June 21,1904.

Application filed June 24, 1903- To aZZ whmn it may concern:

Be it known that I, JOHN G. EBKEN, acitizen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented'certain new and useful Improvements inVehicle Brakes, of which the following is a specification.

My invention relates to an improvement in frictional band-brakes forcarriages, wagons, bicycles, and the like; andits consists in havingcertain novel features shown in the drawings and described in thespecification and particularly pointed out in the claims. In this classof brakes that are used on automobiles and carriages when pressure isapplied friction is not evenly distributed around hub of vehicle, as theusual construction is to have one end of brake-strap-in a fixedposition, whereas in my form of brake when pressure is applied tobrake-rod it draws the ends of brake-strap together and the entireperiphery of brake band is in frictional engagement with ring,

thereby causing an equal wearing upon band Fig. 3, is a section takencentrally of the hub- With parts in elevation. Fig. 4: is a perspectiveview of frictional band. 1 I

Referring to the'drawings and in order to carry my idea into practice,Iemploy a grooved ring 5. This is forced upon hub of wheel, and placedinto groove of same is a frictional band 6. This is lined with amaterial 7 that produces a positive contact with the metal ring whenpressure is applied. For such purpose oiled wood gives the best results,as it does not become heated so readily as metal. This is secured toband by rivets 8. The lower ends of straps 9 are bent around lugs 10 onend of rocker-bar 11 and when this is partly revolved by the movement ofbrake- Serial No. 162,894. (No model.)

1. In a vehicle-brake, a hub, a hub-band with an annular recessextending inwardly from its outer edge, a brake-band comprising a stripof metal increased in width from a point near one end to a point nearthe opposite one, the wider portion of the brake-band extending into therecess and being of such rigidity as to bear on the hub-band when theends of the strip are drawn, a rock-bar to which the ends of thebrake-band are connected, and means for rocking the bar. 7 2.
